Patent CH-652339-A5 (CH)
Title: Process and device for producing a plastic bottle provided with a closure thread
Inventor: HANTICH GERHARD DR
IPC: B29C49/00
Filed: 1981-11-18
Abstract: Plastic bottles with a low-germ, preferably sterile, interior volume are produced by extruding a tube of plastic material, then cutting off a tube piece (parison) and inflating this tube piece in a blow mould by means of a blowing mandrel. The blowing tulip thus formed is melt-closed at the unfilled plastic bottle so as to be airtight and, after the shaping of the plastic bottle, is left on the latter sealed in an airtight manner. The airtight melt-closing of the blowing tulips can be carried out by exerting pressure on the still-fusible hot blowing tulip wall, but also by, directly after shaping, fusing two plastic bottles together with their blowing tulips pressed against one another. A device serving for carrying out the process has, adjacent to the introduction opening of the blow mould (3), a pinch device, in particular pinch jaws (13), for the blowing tulip (8). <IMAGE>

Title: Vapour condenser - esp for use in low gravitational field environments, ie in space applications
IPC: F28B1/00
Filed: 1971-01-26
Granted: 1972-09-15
Abstract: In the classic refrigeration cycle difficulty is experienced with the condenser when the cycle is used in a region of low gravitational field or is subject to disorientation. To overcome this the condenser makes use of the capillary action of a porous wall. The wall must be capable of retaining a certain volume of liquid and must allow the condensed gas to flow through the wall to be collected on the other side. Typical types are made of metallic powder reacted to provide a suitable porosity.
